Add the STACKPROTECTOR symbols to the script that generates the symbols that should not be removed by the use of LTO when linking a shared object. This prevents a fail to build due to link errors.

It is OK to add these new ones, but here you seem to be adding lots of other things also. So far we are only allowing linker lists. So can you update this to allow just linker lists and stack_chk? Perhaps egrep (_u_boot_list_2_|__stack_chk_) or similar?
